This shapefile contains information about the shallow-water (<40 meters) geology and biology of the seafloor in Coral Bay, St. John in the U.S. Virgin Islands (USVI). It was created by manually delineating and classifying habitats visible in a 0.3x0.3 meter aerial photograph mosaic, and by using edge detection algorithms and boosted regression trees to automatically delineate and classify habitat features visible in 0.3x0.3 meter LiDAR surfaces. Habitat features less than 100 square meters were not delineated from the orthomosaic, and were removed from habitat polygons derived from the LiDAR surfaces using ET Geowizards ArcGIS extension. Manually delineated habitat polygons were digitized at a scale of 1:1,000. Habitat polygon boundaries derived from the LiDAR surfaces were smoothed in ArcGIS to more closely match the 1:1,000 scale used for manual digitizing. Georeferenced underwater video & photos were used to train the analyst and algorithm to classify the major and detailed geomorphological structure, percent hard bottom, major and detailed biological cover and live coral cover for each polygon. The thematic accuracy of the map was assessed qualitatively by local experts and quantitatively using randomly sampled locations stratified by detailed geomorpholoigcal structure type. Thematic accuracies for major and detailed geomorphological structure, percent hardbottom, major and detailed biological cover, live coral cover and dominant coral type were: 93.0%, 75.1%, 86.2%, 86.5%, 74.5%, 83.3% and 88.2%, respectively. These thematic accuracies are similar to the thematic accuracies reported for other NOAA benthic habitat mapping efforts around Buck Island in St. Croix (>81.4%), in St. John (>80%), in the Main Eight Hawaiian Islands (>84.0%) and in the Republic of Palau (>80.0%).
Coral reef ecosystems in the U.S. Virgin Islands and throughout the U.S. Caribbean are under increasing pressure from environmental and anthropogenic stressors that threaten these important marine communities. To better evaluate and address these threats, a baseline understanding and periodic evaluation of the benthic communities and associated living marine resources is needed by scientists and resource managers. Habitat maps, in particular, are an integral component to this process because they provide a spatially explicit representation of benthic structure and biological cover. This habitat map of Coral Bay, St. John was created by NOAA to: (1) inform local managers as to the current distribution of resources, (2) provide a point of comparison for past and future mapping efforts, (3) help locate sensitive marine communities, and (4) guide monitoring efforts and prioritize management actions.
